Post-COVID-19 sequelae

I had COVID-19 two months ago. However, I am still suffering from a cough.

My chest hurts so much that sometimes I even vomit when I cough. I feel a foreign body sensation in my throat, but the results of the throat endoscopy are normal.

Because I can't sleep properly due to coughing, my quality of life decreases day by day.

How did those of us with lingering symptoms from COVID-19 recover? Please share your tips.
